Usage

From source file:ComponentTree.java

/**
 * This main() method demonstrates the use of the ComponentTree class: it
 * puts a ComponentTree component in a Frame, and uses the ComponentTree to
 * display its own GUI hierarchy. It also adds a TreeSelectionListener to
 * display additional information about each component as it is selected
 *//* w  w w. j  a  va 2  s.  c  o m*/

    // Finally, set the size of the main window, and pop it up.
